The energy storage system (ESS) is a system that stores electricity in a storage device (battery) and supplies it
when power is needed to increase the energy efficiency and stabilize the power supply system.
when power is needed to increase the energy efficiency and stabilize the power supply system.
Increased energy efficiency
through the convergence
of the ESS and PESS-EMS
Processing, analysis,
and control of energy information
Provision of diverse electric power service
information through the website
and smartphone application
Time-of-use (TOU) pricing and charging
and dischargingschedule based
on a demand-response program
Peak load management /
Frequency adjustment /
Improved power quality /
Voltage adjustment and management
Application Effects
Reduction of electric charges through reduction of peak load
Additional reduction of electric charges during maximum load hours
Convenience in operation through different electric charges at different times
50% discount rate applied to ESS charging rates at night
